Peugeot 407 Reduced Engine Power

Hey, I had a similar issue with my 407! Was it after any recent work? Did you check for any dashboard lights or use a scanner? Sounds like what I went through…

No recent work, just happened. Check engine light is on. What did yours end up being?

Mine was some dodgy chip tuning from a third-party provider that caused all sorts of problems. Best get a car diagnostic done. I'd suggest going to a workshop, they should be able to read the error memory. Cost me 180€ to fix in the end.

Thanks for the advice. Took it in and you were spot on – faulty chip tuning! All sorted now.
